Preparation and Properties of TiB2 Coating against Erosion by Molten Al-12.07wt.%Si Alloy

TiB2 protective coating was prepared in the 310S container wall to improve the life of the container and achieve long-term protection purposes, and also studied the properties of TiB2 coating with anti-heat shock, mechanical and anticorrosion to molten Al-12.07%Si . The results showed that the anti-heat shock properties of the coating was good, bonding strength between coating and substrate was high, the corrosion resistance was improved under certain limited temperature, and the life of container was also remarkable enhanced.
